MAGNETIC MOTOR.

Application filed February 27, 1924.

T 0 all whom it may concern:

Be it known that I, CHARLES C. Pownns, a citizen of the United States, residing at Big Creek, in the county of Fresno and State of California, have invented a new and Improved Magnetic Motor, of which the following is a specification.

My invention has for its object to provide a magnetic motor of a simple and inexpensive structure and of a novel form or design; one which can be used as a novelty for driving window display devices or be used for such other purposes for which it may be adapted.

Generally the invention comprises a field magnet having a straight base portion with a large and a small hook, the ends or extremities of which constitute the magnetic pole pieces between which are located a rotor which consists of an annular iron ring with iron or steel blades projecting therefrom around the circumference, around which blades the pulling force of the magnet poles acts, a suitable energizing coil with make and break circuit commutator being provided in cooperation with the rotor and the magnet core.

In its more detail nature, the invention resides in those novel features of construction, combination and arrangement of parts, all of which will be first fully described, then be pointed out in detail in the appended claims and illustrated in the accompanying drawing, in which:

Figure 1 is a side elevation of a preferable embodiment of my invention.

Figure 2 is a plan View of the same.

Figure 3 is a cross section of the rotor.

In the drawing, in which like numerals of reference indicate like parts in all of the figures, 1 is the base portion of the magnet on which the energizing coil 19 may be mounted, and 2 and 3 designate the backwardly curved or hook-like ends whose terminals constitute the pole pieces of the magnet. Mounted between the pole pieces of the magnet on an axis 6 supported in suitable non-magnetic bearing brackets 4 is the rotor which includes an insulating axle 5 carrying iron rings 7 in which the blades 9 of magnetic material are set in slots 8, the blades 9 being preferably inclined to the radius of the rotor, as shown in Figure 1.

10 is the insulated base of a commutator or circuit breaker which carries a contact Serial No. 695,546.

ring 11 for engagementby the brush 13 mounted and insulated at 14 to be connect ed with one terminal of a source of current supply 17, the other terminal of which is connected by wire 18 in circuit with the magnet coil 19. The commutator also includes insulated segments 12 (one for each blade 9) to be engaged by the brush 15 insulated and mounted at 16 and connected through a wire 18 with the magnet 19 so to complete the magnet circuit through the make and break contacts 12 of the commuta tor.

It should be understood that the base of the contacts 12 in relation to the blades 9 is such that the electric circuit is broken just prior to the instant the dead or equalized position of the rotor with regard to the magnetic lines of force is reached and as soon as the blade passes the neutral point the circuit is again made so as to cause magnetic action to take place on the next following blade and so on. In this way, a series of impulses is given to the blades of the rotor, and by reason of the provision of the iron rings 7, which act as fly wheels, the rotor is kept in constant rotation.

It will be observed that the axis of the rotor is so positioned that the magnetic pole pieces have their end portions extending in directions approximately tangential to the periphery of the rotor, as this lends a novel form or appearance to the device which will make it especially adaptable as a toy motor, for window display and similar operations.

From the foregoing description, taken in connection with the accompanying drawings, it is thought the complete construction, operation and advantages of my invention will be readily understood by those skilled in the art.

What I claim is:

1w In a motor comprising a magnet having hook-like ends in combination with a rotor mounted between the ends, the ends of said magnet constituting polar projections, said polar projections extending in a direction approximately tangential to the periphery of the rotor, said rotor including rings of magnetic material and blades of magnetic materialprojecting from said rings around the periphery thereof.

2. In a motor comprising a magnet having hook-like ends in combination with a rotor mounted between the ends, the ends of said magnet constituting polar projections, said polar projections extending in a direction approximately tangential to the periphery of the rotor, said rotor including rings of magnetic material and blades of magnetic material projecting from said rings around the periphery thereof, a make and break circuit commutator rotating With the rotor, an energizing coil on the magnet in cooperation with said circuit commutator, said commutator and said coil having provision for connection With a source of electric energy.
